Stock BMW E46 325 vs E46 330 Dyno Test - How Big is the Real Difference?

What does a STOCK BMW E46 really make on the dyno?

In this video, we dyno test two completely stock BMW E46s — a 325i and a 330i — back to back to see how much power they ACTUALLY put down before any modifications.

Most people jump straight into mods, but very few ever establish a real baseline. So before touching intakes, exhausts, tunes, or cams, we wanted real numbers straight from the dyno.

In this video:
• Stock BMW E46 325i dyno results
• Stock BMW E46 330i dyno results
• M54B25 vs M54B30 real-world horsepower
• How drivetrain loss affects advertised power
• Which one offers the better starting point for mods

If you’re planning to modify an E46 — or just curious whether BMW’s factory numbers hold up — this is a must-watch.
